Abstract: ABSTRACT OF THE DISCLOSURE            Gypsum plaster prepared from gypsum rock having a substantial salt content is rendered more suitable for manufacturing processes such as the manufacture of gypsum board by rapid and intimate mixing with a flow of water followed by rapid separation of the bulk of the water, the recovered purified wet or damp plaster being used at once in the manufacturing process before an unacceptable degree of hydration has occurred.  It is preferred to use for the washing cold water, say up to 30° and to add no retarder or other additive at the washing stage in order to minimize cost and avoid interference with the subsequent manufacturing process.  The time elapsing between contacting the plaster with water and recovery of wet purified plaster preferably does not exceed 30 seconds.  A rotary or vertical mixture may be used and the preferred means for rapid separation is a continuous decanting centrifuge having a cone angle not exceeding 7°.

Abstract: ABSTRACT OF THE DISCLOSURE       A universal joint is provided, and more specifically a constant-velocity type of universal joint particularly for use in a drive train of a front wheel drive vehicle.  The universal joint resembles a flexible bellows-type of joint as viewed from the side in elevation but is made primarily of elongate elements which are placed in tension to transmit torque from one shaft to another.  The body of the universal joint has at least two large diameter portions and a smaller diameter portion there-between with the elongate element extending diagonally in both directions between the peripheries of the large diameter portions to provide torque transmittal in both directions.  The universal joint preferably is produced from a contiguous flexible element which is moved transversely or back and forth beyond two cir-cular core members which are positioned coaxially and spaced apart a distance equal to that of the large diameter portions of the universal joint.  The circular members are then rotated as the elongate element is moved back and forth to provide the diagonally-extending bridging elements or lines and also form anchor portions or chords at the outer faces of the circular members.  The crossing points of the bridging lines form the small diameter portion of the universal joint.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a medical slide case hav-ing structural features to facilitate the storage and transport of medical slides while preserving the slides in an uncontami-nated and undamaged condition.  Characteristically, in the past, a sample speciman obtained from a patient is placed on a cleaned or sterilized clear glass medical slide and treated at the examination situs.  However, during storage and trans-port to the medical lab, the slide is placed in an enclosure case and may arrive at the medical laboratory in a contami-nated or damaged condition, frequently necessitating that the sample be retaken.  It is an object of the invention to-provide a medical slide case to accommodate the storage and transport of a medical slide from the patient examining situs to the laboratory situs in an improved and facile manner.  In accordance with the invention, there is provided a medical slide enclosure case comprising non-separable congruently mirrored segments of molded plastic.  The segments are joined by an integrally molded thin hinge line.  Case closure is accomplished by molded hooks on the segments in snap closure alignment with molded wall edges and opposed to the hinge line.  Case segments include internal walls defining a slide receiving cavity.  The cavity includes spacer ledges to main-tain the received slide surfaces in spaced relation to the inner case surfaces.  The case includes a defined finger cavity adjacent the slide cavity facilitating easy insert and removal of the medical slide from the case.

Abstract: ABSTRACT OF THE DISCLOSURE There is provided an apparatus for topping trees, in which a carriage is movable along an elongated rail.  The carriage defines an upper longitudinal recess capable of receiving a trunk of a tree, and a pair of topping blades are mounted to either side of the central recess longitudinally offset therefrom, with each blade pivoting about an axis substantially normal to the direction of carriage movement, between a first position in which the blade is out of interfering relationship with a tree or trees located in the central recess, and a second position in which the blade extends at right angles to the direction of carriage movement.  The two blades in the second positions are aligned and have their cutting edges juxtaposed at about the mid-plane of the recess.  The carriage is arranged to top trees held stationary with respect to the rail, while the carriage moves in one of the forward or rearward directions.          The blades pivot from the first or second position as the carriage is travelling in one direction, and bite into the trees which are located in the recess.  The tree motion with respect to the carriage urges the blades further toward the second positions thereof, thereby causing the blades the cut through the tree.  The means which pivot the blades toward the second position causes the blades to move at a rate such that the component of motion of the cutting edges   parallel with the rail is smaller than the speed of the carriage with respect to the rail, such that the biting of the blades into a tree causes the tree itself to continue the closing movement of the blades toward their second positions, thus relieving the closing means from having to exert the force necessary to cut through the tree.

Abstract: ABSTRACT OF THE DISCLOSURE A smash-recoverable printing blanket having a substantially uni-form thickness and method of making the same are provided.  The blanket comprises a plurality of layers including at least one layer which swells upon being contacted by a liquid.  A plurality of microcapsules are dis-posed within the blanket, with the microcapsules containing the liquid. The microcapsules are ruptured upon smashing the blanket.  This releases the liquid contained therewithin against the one layer thereby causing swelling thereof and restoring of the adjacent layer substantially to its original position prior to the smashing, in order to define the uniform thickness.  Thus, when the blanket is subjected to excessive compression or shashing, it is self-recovering.  In other words, the construction of the blanket is such that it restores itself to its original thickness, without stopping or removing the damaged blanket or stopping the associated printing apparatus or press.

Abstract: ABSTRACT OF THE DISCLOSURE           A process involving a static mixer for continuous production of metal alloy is such that molten metal is passed through a filter bed of loose particulate material exposed to atmospheric pressure.  The alloying addition is made to the metal via a proportioning and feed device as the metal enters the filter bed.  As a result the alloy components are dissolved in the molted metal and, due to the repeated division and reuniting of the streams of charge in the bed, the alloying elements are mixed with the metal before leaving the mixing chamber.  The degree of mixing can be changed by changing the size of particles in the granular bed.  The static mixer of this invention avoids the wear and high maintenance costs inherent in mechanical stirring devices.

Abstract: ABSTRACT OF THE DISCLOSURE        A plastic bucket lid is adapted for removable attachment adjacent its periphery to a bucket.  The lid defines an annular open depression adjacent its periphery, and, positioned outwardly from the depression, an annular locking slot for receiving and holding the lip of a bucket.          In accordance with this invention, radially-positioned reinforcing fins are carried by the lid within the annular, open depression to restrict the flexing of its outer wall.          This, in turn, has been found to reduce the tendency of the lid to be knocked off of a bucket upon being dropped or the like.  Preferably, an outwardly positioned annular projec-tion is placed in the locking slot  which defines an angle of 80° to 100° to the plane of the annular walls defining the locking slot for improved retention of the lid to the bucket.
